Cognitive loss from severe Covid equivalent to 20 years of ageing: Study

Survivors scored particularly poorly on tasks such as verbal analogical reasoning, a finding that supports the commonly-reported problem of difficulty finding words. They also showed slower processing speeds.

Cognitive loss from severe Covid equivalent to 20 years of ageing: Study

Cognitive impairment, as a result of severe Covid-19, is similar to that sustained between 50 and 70 years of age and is the equivalent to losing 10 IQ points, finds a study.

The results of the study, published in the journal eClinicalMedicine, suggest the effects are still detectable more than six months after the acute illness, and that any recovery is, at best, gradual.
